Have you seen the work of French comics artist Jaques Tardi?
His style may at first glance appear to be sketchy and
rudimentary, but just try and imitate it!
My favourites are his series about the Parisian detective Nestor Burma, where you can really
follow the action street by street. There must be a staggering amount of research, even more
in his 4-volume series about the 1870 Paris Commune ' Le Cri du Peuple'. He's known in
France as 'The master of black and white'- with good reason
